Hi all,

Yes, another spin-down problem. If any UberSlugger out there can help with this I'd be really grateful. I've read everything I can find in the groups and wikis; I think I've done everything right, but I just can't get it to work.

First, the hardware:

NSLU2, runing Unslung V2.3R63-uNSLUng-6.8-beta

Buffalo Drivestation 300GB, with sleep timer set to 10 mins. I know this works as it shuts down/wakes up upon connection, and sleeps when connected to a Windows machine.

The problem - the hard disk is accessed every 5 seconds. The drive's LED shows a very brief flash , so clearly 'something' is happening every 5 seconds. Running dmesg shows this line:

kjournald starting. Commit interval 5 seconds

so this looks like the journalling writes every 5 seconds. If so, why doesn't everybody else get this problem?

#!/bin/sh# /unslung/rc.local# A diversion script to remount the drive(s) without access# times being recorded (the update of access times can# prevent drives sleeping)

# Usually it is enough just to do /sda1 as this is the usually# the one that holds the system./bin/echo "Remounting /dev/sdb1 with noatime"/bin/mount -o remount,rw,noatime /dev/sdb1/bin/echo "Remounting /dev/sdb2 with noatime"/bin/mount -o remount,rw,noatime /dev/sdb2

# return 1# EOF - include this line

I think the first thing to check is to see if the mounts are correct My knowledge of Linux isn't brilliant, but it looks like dev.state is mounted on /dev/sdb1. Is this supposed to be like this? Could someone compare there system, please?
